Layered gelatin desserts are created by preparing each flavor of gelatin according to package directions, pouring flavors into a container one at a time, and allowing each flavor to slightly chill in the refrigerator until set. Yogurt, cream cheese and whipped topping are often used to create creamy layers.
A classic rainbow gelatin dessert is made by dissolving one flavor of gelatin in hot water and allowing it to chill for a specified period of time. Remove the gelatin from the refrigerator, and pour it into a container such as a glass or mold. Some recipes call for adding yogurt to a reserved gelatin mixture and spooning it on top of the chilled gelatin layer. When the process is repeated using other gelatin flavors, it produces a layered dessert featuring colors such as blue, green, red and orange. Kraft's recipe for Jello-O rainbow cups uses four packages of flavored gelatin; it takes one hour and 50 minutes to make eight individual servings.
